摘要：
This article compares engine performance, combustion, and emissions at part-load in cylinder deactivation (CD) mode versus the traditional spark ignition mode. This comparison demonstrates the applicability of cylinder deactivation for a compact 3-cylinder engine. Experiments have been performed on a multi-point fuel injection engine having a 1000 cc displacement and equipped with an open engine control unit. A response surface approach has been applied to design experiments and parametric engine optimization. The analysis of variance test indicates that the load is the input factor that impacts the deactivation mode most. At 3500 RPM and 45 N·m load, the engine performs best in CD mode, with BSFC, BTE, CP, HRR and UHC values of 332.805 g/kW-hr, 25.26 %, 52.51 bar, 43.24 J, and 10.38 ppm, respectively. The validation test results for CD mode show that the percentage error for the BSFC, BTE, CP, HRR, and UHC responses was found to be 2.86, 2.91, 3.01, 3.47, and 3.97, respectively, within the acceptable range. As compared to SI mode, the current analysis has discovered a considerable decrease in BSFC (11.47 %), an improvement in BTE (12.25 %), a higher CP (80.65 %), a greater HRR (91.74 %), and a decrease in UHC (95.48 %).
